Lamar climbs to 92 Monday before windy Tuesday cools Prowers County
Lamar will see the hottest day of the week on Memorial Day with a high near 92, followed by a windy Tuesday as a low pressure system approaches the Four Corners and pulls strong southerly winds across the southeast plains, the National Weather Service in Pueblo said. Thunderstorm chances run 20 to 30 percent each afternoon and evening from Monday through Wednesday.
Monday is sunny in Lamar with a south-southeast wind 5 to 10 mph increasing to 15 to 20 mph in the afternoon and gusts to 30 mph. A 20 percent chance of showers and thunderstorms develops after 4 p.m. Overnight, the low drops to around 51 with a 30 percent chance of brief evening storms and breezy south-southeast winds 20 to 25 mph.
“Monday will be our hottest day this week, with highs in the 80s to low-90s over the plains,” forecaster Tony Garberoglio wrote in Sunday’s Area Forecast Discussion from the Pueblo office. He added that high-based showers will move off the southeast mountains during the afternoon and evening, with “little to no precip ... expected to hit the ground, mainly just resulting in windy virga.”
Windy Tuesday with storm potential
Tuesday is the windier day of the period. The Pueblo office is forecasting sustained south-southeast winds of 20 to 30 mph at Lamar with gusts approaching 45 mph, partly sunny skies and a 30 percent chance of afternoon and evening showers and thunderstorms. Highs ease to around 85.
No Red Flag Warning was in effect for Prowers County (fire-weather zone 236) as of Sunday afternoon. The most recent Pueblo fire-weather product was a May 18 cancellation for the far southern plains. Still, the combination of dry surface conditions, low humidity and gusts approaching 45 mph warrants caution with any open flame outdoors Monday through Wednesday.
